Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security systems face challenges in accurately matching digital certificates to active ports on devices within a network without requiring third-party access, leading to inefficiencies in certificate management and security verification.
Innovation Solution
A computer-implemented method using processor units to identify certificates, perform internal scans, and match certificate chains with active ports, generating a data structure that includes file paths and metadata for comprehensive security information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If third-party access is used to match certificates with ports, then matching accuracy can be improved, but system complexity and external dependencies increase
Solution Approach 1:
The system performs self-service by implementing internal scanning mechanisms that allow the device to autonomously identify its own certificates and match them with active ports without requiring external third-party tools. The processor executes instructions to scan the device, retrieve certificate information, and perform matching operations internally, eliminating external dependencies while maintaining matching accuracy.
2Measurement precision
If comprehensive certificate scanning is performed, then matching accuracy is improved, but computing time increases
Solution Approach 1:
The system applies preliminary action by performing an internal scan of the device before attempting certificate matching. This preliminary scan identifies all certificates present on the device and stores their information in advance, so that when matching is required, the comparison can be performed quickly against pre-retrieved certificate data rather than scanning during the matching process itself.
3Adaptability or versatility
If internal scanning is used instead of third-party access, then system independence is improved, but measurement capability may be reduced
Solution Approach 1:
The system uses an intermediary approach by implementing an internal scanning mechanism that acts as a mediator between the device's certificates and the matching process. The scanner retrieves port information and certificate information through controlled internal access points, enabling independent operation while maintaining the ability to accurately identify and match certificates with their corresponding ports.

AI summary
A computer implemented method is provided. A number of processor units identify a number of certificates for a device within a network to obtain a file path for each certificate. The number of processor units perform an internal scan of the device to obtain a port number for each active port associated with network protocol on the device. The number of processor units identify a certificate chain associated with each port number based on the network protocol for the device. The number of processor units compare content for each certificate from the number of certificates to the certificate chains for the device to generate a number of matches. The number of processor units generate a data structure including the file path of the certificate for each port on the device based on the number of matches.
